AN205316 - FR, MB91460, Pulse Frequency Modulator
Sep 09, 2017
The PFM is used to generate pulses of a short duration in a long period. This is an alternative to using PWM signals in some applications. The 16-bit pulse frequency modulator consists of two 16-bit down-counters, two 16-bit reload registers, prescalers for generating the internal count clocks and control/status registers.
